Anthropic previews Claude Duet, an always-on background agent

Short answer

Anthropic has put Claude Duet into research preview: an agent that watches your connected apps, sends a morning brief and works in the background without a prompt. It needs approval before sending, paying, signing or deleting. It runs on your existing Claude plan limits, which a hands-on tester burned through fast.

What this means for operators

If you run sales, support or operations at a 10-200 person company, Duet is worth a small trial on one mailbox, not a rollout. Its approval step before outbound messages and payments keeps a human in the loop, and the inbox triage and daily to-do templates map to work your team already does by hand. The cost model needs watching: background checks count against the same Claude plan limits as normal chat, and the one reviewer reported using up session limits within two days. Anything that runs identically every time, such as pulling an amount and due date from a recurring vendor invoice, belongs in a fixed workflow, not an agent that reasons through it on every run. Note also that the native Gmail connector sees one account only, so shared or secondary mailboxes need another route.

Anthropic has released Claude Duet in research preview, according to a Zapier Blog hands-on by Wade Burrell, a Zapier product marketing manager. Zapier sells automation that plugs into Duet, so read its comparisons with that in mind. Duet is a separate app from the Claude chatbot, though you sign in with your existing Claude account.

What it does

Instead of waiting for a prompt, Duet sends a morning brief summarising the most important items across connected apps. It checks those accounts every few hours and messages you only when something needs attention. You choose what it reports and how often. The work runs inside its own virtual machine that you reach through a browser, meaning your phone or laptop can be switched off while it continues. That browser also lets it fill in forms on sites that have no connector.

The app has three tabs: Chat (text or voice), Tasks (background work) and Make, which holds templates such as a daily to-do list and email triage. Tools, projects, memory and skills from your Claude account carry over. Onboarding pushes four first-party connections: Gmail, Slack, Calendar and Google Drive.

Safeguards

Anthropic states that Duet can read, write drafts, and get work ready without asking first, yet it presents its plan and requires sign-off before sending a message, issuing a payment, executing a document, or removing any data. Trading securities and moving money between accounts stay off-limits even with approval. Duet connects through OAuth, so it does not see passwords or sign-in tokens, and any app can be disconnected. Anthropic also reports prompt-injection screening, a classifier for sensitive data and testing by internal red teams and an outside firm. The reviewer's advice is to check what it does, especially early on.

Access and cost

Access is by waitlist for U.S. Pro, Max and Ultra subscribers, on iOS, Android and claude.ai. There is no separate price. Duet shares your plan's limits, and background checks count against them. The reviewer's first couple of days used up all of his session limits, and the app did not make clear which limits applied.

Early findings

After a few days, the reviewer found setup quick and the proactive behaviour useful. Overnight, Duet matched Google security alerts to the connections he had just made and summarised them unprompted. The Tasks tab starts empty and offers to scan your tools, and two tasks were running by that morning. The downsides were the fast limit use, a Gmail connector limited to one account, and the general risk that an agent misjudges urgency. These are a few days of first impressions on a preview product, not a verdict.
